Shape-shifters: shape-memory polymers find use in medicine and clothing

Article Abstract:

Shape-memory polymers are being used in polyurethane-based fabric for cold-weather clothing and medical devices, and being tested as part of automobile bodies. The polymers are affected by heat to return to their original shape.

Nanorobot construction crews

Article Abstract:

The idea of molecular manipulation inherent in nanotechnology is discussed. The work of futurist K.Eric Drexler and Ralph Merkle is studied and developments in microelectromechanical systems at Zyvex are examined.

Artificial muscles

Article Abstract:

Electroative polymers (EAPs) act as electrically controlled muscles, which holds promise for becoming the artificial muscles in future. It will take time to be strong enough to compete with the human arm.
